Specification of Iietters Patent.

Patented Feb. 24, 1914:.

Application filed October 19, 1912. Serial No. 726,801.

To all whom it may concern:

Be it known that I, WARNER E. SMITH, a citizen of the United States,residing at Rule, in the county of Haskell and State of Texas, haveinvented certain new and useful Improvements in Cultivators, of whichthe following is a specification, reference being had therein to theaccompanying drawing.

This invention relates to cultivators and has for its object theproduction of a cultivator for cleaning the beds where the plants areplanted down deep in the ground so as to rid the surface of the groundfrom weeds which grow up prior to the appearance of the plants or cropswhich have been sown in the field.

Another object of the invention is the production of an efiicientmechanism where the cultivator blades may be adjusted to difierentangles and the weed cutting knives may also be adjusted to differentheights relative to the form of the sled.

With the above and other objects in view this invention consists incertain novel combinations, constructions and arrangement of parts asWill be hereinafter fully described and claimed.

In the accompanying drawings :Figure 1 is a top plan view of thecultivator. Fig. 2 is a side elevation thereof. Fig. 3 is a centrallongitudinal sectional view of the cultivator. Fig. 4 is a detailperspective view of the adjusting clip for holding the barrow bladesupporting arms in an adjusted swung position. Fig. 5 is an enlargedview through the connecting member for the harrow blade supporting armand the connecting link for securing the arm to the frame of the harrow.

By referring to the drawings by numerals it will be seen that 1designates the platform of the sled which is supported bv the usualrunners 2 having metallic protector bands 3 upon their lower edges. Tothe front end of the platform 1 is connected a draft connecting member 4to which the double tree or other draft connection 5 is secured. A seatsupporting brace 6 is also carried by the front platform and upon thisseat supporting brace 6 is mounted a seat 7. A rack member 8 is carriedupon each side of the sled and is provided with rack teeth 9 upon itsouter edge, which rack teeth are adapted to be engaged by the handles orarms 10 of the cutting knives 11. These handles or arms 10 are connectedto the sides of the passes transversely of the platform 1. This coilspring 15 is adapted to hold the arms 10 in engagement with the rackteeth 9 of the rack members 8 so as to hold the knives 11 in an adjustedswung position. It will be seen that by swinging the arms 10 in themanner just described and placing the same in the teeth 9, the knives 11may be held in the desired pitched relation to efficiently cut the weedsjust above the ground. It will be further understood that the knives maybe adjusted vertically of the runners 2 so as to prevent the knives fromcutting into the ground in case the ground should be soft and therunners should sink in the ground below their lower edges. The purposeof these knives is to out the weeds just above the ground and it is,therefore, advantageous to have the knives adjustable so as to preventthe knives from becoming unnecessarily dull by coming in contact withthe ground.

A yoke member 16 straddles each runner 2 near its rear end and to eachyoke member is connected a link 17 so as to allow the link member to beswung upwardly to any desired position. This link member 17 is providedwith a circular head 18 having a toothed face upon its upper edge forengaging the toothed face of the lower edge of the head 19 of the dragbars 20. A bolt 21 passes through the head 18 and the head 19 forholding the drag bars 20 in an adjusted position to prevent the dragbars from being swung laterally relative to the platform 1. Harrowblades 22 are supported by the rear ends of the drag bars 20 asillustrated in Figs. 1 and 3. Harrow arm receiving clips 23 are carriedby the rear end of the platform 1 and these clips 23 comprise an elongated body 24 having integral upwardly extending parallel arms 25 forreceiving the drag bars 20 and holding the same against swingingmovement. Each of the clips 23 is provided with an arcuate groove 26through which passes a bolt 27 for holding the clip 23 in an adjustedposition. It should be understood that these clips may be swung upon theplatform 1 to such a position as to have the harrow blades or harrowsupporting drag bars 20 extend at any desired angle relative to theplatform 1.

Chains 28 are connected to the drag bars 20 and have their upper endsconnected to a standard 29 by means of the bolt 30, and it bars forholding said drag bars in adjusted position, an elongated body securedadjacent each side of said platform, each body provided with verticallyextending parallel clips, said drag bars adapted to fit between saidclips for preventing said bars from swinging laterally.

should be understood that these chains ma5 A cultivator comprising aframe, yoke be so adjusted as to support the drag bars up at anoperative position or to the position shown by the dotted lines in Fig.3.

From the foregoing description it will be seen that an eflicient andsimple apparatus has been produced whereby the weed cutting knives maybe adjusted to accommodate the difierent conditions of the ground overwhich the sled is passing and also that the drag bars may also be swunglaterally and vertically of the platform 1 so as to be brought to thedesired positions. It will be further obvious that a very simple andeflicient device has been produced which may be manufactured at aminimum cost.

Having thus described the invention what is claimed as new, is

l. A cultivator comprising runners, a platform carried thereby,vertically extending yoke members carried by said runners,

link members connected to said yoke mem bers and capable of being swungvertically thereof, drag bars secured to said link members, rack teethformed upon said links and said drag bars, the teeth of said linksadapted to engage the teeth of said drag bars, bolts passing throughsaid links and drag members secured to said frame, links secured to saidyokes and adapted to swing vertically thereon, drag bars piyotallysecured to said links and capable of swinging laterally thereto, wherebysaid drag bars have free vertical movement and are capable of swinginglaterally, an elongated body adjustably secured to said frame, said bodyprovided with vertically extending parallel clips, said drag barsadapted to fit between said clips for holding said drag bars in adjustedposition, each of said elongated bodies provided with a curved slot, abolt passing through said slot for holding said body in adjustedposition, said body capable of mov ing upon said bolt for moving saidclips and. drag bars laterally upon said frame, and chains carried bysaid frame and engaging said drag bars for holding the same in aninoperative position.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
